As shown in the figure, ARID1A or ARID1B expression was related to immunosuppression in 517 lung adenocarcinoma (LUAD) samples and 501 lung squamous cell carcinoma (LUSC) samples, which is mainly characterized by significant reductions in the abundances of activated CD8+ T cells and activated dendritic cells (DCs). The gene discussed is ARID1B; the disease is squamous cell lung carcinoma.
